Title: Heading reference system with remote-mounted sensor
Inventor: OOMKES DANIEL L
IPC: G05D1/06
Filed: 2007-07-16
Abstract: A navigation system for an aircraft includes one or more wing-mounted sensors whose outputs are effected by the flexing of the wing during flight. The navigation system corrects for these errors using measurements of actual wing flex taken during an initial flight and thereafter assumed to be valid for all subsequent flights and for all aircraft using the same type of airframe. The actual measurements of wing flex define a wing flex correction factor that the navigation system may adjust during flight to reduce or remove residual errors. The wing flex correction factor accounts for all three types of possible wing flex: pitch, roll, and yaw flexing.

Filed: 2004-04-29
Abstract: Articles made of shape memory alloys having improved fatigue performance and to methods of treating articles formed from those materials by pre-straining the articles (or desired portions) in a controlled manner so that the resultant articles exhibit improved fatigue performance. The shape memory articles are preferably medical devices, more preferably implantable medical devices. They are most preferably devices of nitinol shape memory alloy that is superelastic at normal body temperature. The pre-straining method of the present invention includes the controlled introduction of non-recoverable tensile strains greater than about 0.20% at die surface of a desired portion of a shape memory alloy article. Controlled pre-straining operations are performed on shape-set nitinol metal to achieve non-recoverable tensile strain greater than about 0.20% at or near the surface of selected regions in the nitinol metal article. The pre-straining operations result in a significant increase in fatigue life of the selectively treated regions and an overall improvement in the fatigue performance of the device.
